This sort of well researched and reasonable speculation is exactly what All Yesterdays was about. I just wish depictions such as this would find their way into mainstream paleontology media in some form or another and influence popular ideas about prehistory to some degree.Devin Myersnoreply@blogger.comtag:blogger.com,1999:blog-3653345901774701895.post-54442341143935276132015-09-22T14:58:40.568-07:002015-09-22T14:58:40.568-07:00I'm skeptical of whether any gorilla actually ...I'm skeptical of whether any gorilla actually has that much space between the top of it's skull and the top of it's head. It looks like the illustrator for the figure used a female or young male gorilla skull and outlined a large male silverback's head on to it. The hump in silverbacks is composed of neck musculature in the back and temporalis muscles on top of the cranium, but these are supported by insanely large sagittal and nuchal crests on the skull -- thus having clear osteological correlates. Gorillas without massive sagittal and nuchal crests (like the skull in the above figure), also seem to lack a large hump on their head and neck. Or, at least, I've never seen anything to suggest the contrary. Has anyone ever seen a published gorilla dissection that shows otherwise?Dallas Krentzelhttps://www.flickr.com/photos/31867959@N04/noreply@blogger.comtag:blogger.com,1999:blog-3653345901774701895.post-45290995518036179462015-09-19T19:57:54.577-07:002015-09-19T19:57:54.577-07:00Quote tags not goin', back to ye olde quotatio...Quote tags not goin', back to ye olde quotation marks:<br /><br />"Wouldn't basing off birds and reptiles be a better option?"<br /><br />Isn't that what this blog post was about...?<br /><br />"I decided to revisit this image this week to boost the sauropod content of Recreating an Age of Reptiles (coming soon, I swear!). In doing so, I decided to conduct some more research into the likely nature of non-avian dinosaur fatty tissues...<br />I suggest we err on the side of caution and maintain the diapsid condition, principally locating them around the tail base and abdomen."<br /><br />If you want an idea of just a few of those diapsids with obvious fat stores, that Mark is talking about, look up eublepharid geckos, especially Eublepharis (plenty of pet photos online) and Hemitheconyx. (The clue is in the name ;) ) Also Heloderma, Tiliqua, and Uromastyx. As mentioned, other lizards and crocs have wide tail bases, but I think the effect's especially pronounced in these genera due to their desert habitats and the fact their tails don't go too much further than 'base'.<br /><br />On the blog post: nice! The old camarasaur hump didn't offend, but I definitely like the diapsid option. (Is the fact it's caring for a single offspring a more controversial depiction?) :) After reading some other bits about reotilian tail recently I start to wonder, do those mammals have to put fatty humps on the back and neck because their caudal 'quipment is just not up to the task?Warren JBhttps://www.blogger.com/profile/11743987856127631574noreply@blogger.comtag:blogger.com,1999:blog-3653345901774701895.post-40192850543739699802015-09-19T19:49:14.504-07:002015-09-19T19:49:14.504-07:00This comment has been removed by the author.Warren JBhttps://www.blogger.com/profile/11743987856127631574noreply@blogger.comtag:blogger.com,1999:blog-3653345901774701895.post-72516147614065865652015-09-19T06:58:13.567-07:002015-09-19T06:58:13.567-07:004/5* pictures, my apologies.4/5* pictures, my apologies.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3653345901774701895.post-84231644897505291782015-09-19T06:57:09.757-07:002015-09-19T06:57:09.757-07:00While I accept the idea of fatty deposits and othe...While I accept the idea of fatty deposits and other lumps of tissue exist on dinosaurs, is it really accurate to be assuming this based upon mammals? 5/6 out of those pictures are mammals and the one that is a reptile is rather close (in relation to the mammals being close) to its skeleton. Wouldn't basing off birds and reptiles be a better option?

(Also: shipping is a tiny fraction of the ludicrous price that Lulu charges for folding a book into a bit of cardboard and bunging it in the post.)<br /><br />It might be worth getting an online quote from somewhere like Lightning Source: https://www.lightningsource.com/ShippingCalc.aspx<br />I'm getting £700 including shipping for 100 copies colour printed in 70lb white paper. That goes up to £978 for hardbacks, so a bit under a tenner per copy. It's more hassle, and you're gambling that you'll be able to shift all the stock, but it's WAY better value.<br /><br />Mike Taylorhttps://www.blogger.com/profile/06039663158335543317noreply@blogger.com
